Deposits and Withdrawals
Spawn's non-custodial architecture means your funds never leave the on-chain layer. When you deposit, you're moving assets directly into the vault contract on Base. When you withdraw, you're calling that contract directly to take them back. Spawn doesn't hold your funds - the contract does, and you control the exit.
Depositing
From Base: Deposit directly into the vault with near-instant confirmation. Once your deposit is confirmed on-chain, your balance is available to trade immediately.
From other chains: If you're coming from a non-Base chain, Spawn handles the cross-chain transfer automatically. You initiate the deposit from your origin chain and the funds arrive in the vault on Base - no manual bridging step required. See Cross-Chain Access ->
There's no minimum deposit threshold and no gatekeeping on who can deposit.
Withdrawing
To withdraw, you request a withdrawal from the platform. The operator signs it, and you call the vault contract to execute. Your funds move directly on-chain to your wallet - no intermediary, no delay beyond the on-chain confirmation.
You can withdraw at any point. There's no lock-up period and no approval required from Spawn.
What This Means for You
Non-custodial participation has a practical implication beyond principle: Spawn's operational status never determines whether you can access your funds. Because withdrawals are executed through the on-chain contract, your ability to retrieve your assets doesn't depend on the platform being available.
During the bonding curve phase, your trading balance lives in the vault and is reflected in your off-chain account state. After graduation, token claims and on-chain balances follow the token's post-graduation mechanics. See After Graduation ->
